radius Lightning用 DACアンプ

radius(ラディウス) DACアンプ
RK-DA70L(iPhone Lightning用)
新品で購入しました。断線や傷もなく問題なく使用できます。

MFi認証を取得しており、iPhoneなどで手軽にハイレゾ再生を楽しむことができるφ3.5mmジャック搭載の超小型DAC/AMPです。
日本オーディオ協会のハイレゾマークを取得しており、楽曲再生時のビットレート/サンプリングレートは、CD音源(16bit/44.1kHz)の約17.4倍もの情報量を持つ32bit/384kHzまで対応しています。DSD再生の場合、最大5.6MHzのDoP再生が可能です。

SoCとしてESS Technology社製「ES9270C」を搭載。同社の特許技術である「Hyperstream DAC」と「タイムドメイン‧ジッターエリミネーター回路」を備え、高水準のオーディオ特性を実現します。一般的にオーディオ特性は、定格負荷のもと単純信号波形(正弦波や方形波)の入力時に得られる出力特性である「静特性」が指標とされます。しかし、実際の楽曲再生時は入力信号波形の振幅や周波数が一定ではないため、非周期的な定常ノイズが発生し、特性を悪化させています。「Hyperstream DAC」は、独自のノイズシェービング技術により楽曲再生時の出力特性である「動特性」における定常ノイズを除去することができます。さらに、「タイムドメイン・ジッターエリミネーター回路」により、D/A変換を行う際に発生しうるオーディオマスタークロックの時間軸上でのブレを補正することで、より高精度な信号変換を実現。定位の安定した非常にクリアなサウンドを再生します。

「ES9270C」はG級アンプを備えています。再生する楽曲などの音声信号レベルが低いときは、より低い電源電圧を使用し、信号レベルが増加すると、自動的に適切な電源電圧に切り替わります。信号レベルの大きさに合わせて効率良く動作することで、接続端末の電源使用量を最適化し、省電力ながらも音声の出力レベルを問わず常に再現性の高い楽曲再生が可能です。

筐体素材には、軽量で高剛性のアルミニウムを採用。全長はわずか10cmでコンパクトです。

※あくまで中古品となりますので、ご理解のうえノンクレームノンリターンでお願いします。
